Limiting the Amount of Tags for Acts as Taggable On
- by bob
Hello, I am wondering how to limit the amount of tags, the tag_cloud function returns for this plugin. http://github.com/collectiveidea/acts-as-taggable-on
Also, I would like to know how to order it so that it orders the tags by the highest count. So the most popular are at the top.
I tried to do @tags = Post.tag_counts_on(:tags, :limit = 5) but that did not work.
Controller:
class PostController < ApplicationController
def tag_cloud
@tags = Post.tag_counts_on(:tags)
end
end
View:
<% tag_cloud @tags, %w(css1 css2 css3 css4) do |tag, css_class| %>
<%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %>
<% end %>
Thanks!
